src/prs_db_builder.c: Add the same bail-out logic to prs_db_builder as  to prs_server (see previous commit), so that it doesn't keep trying to  work when config file parsing has generated an error.  More work needs  to be done in this area in both programs.

Also fixed yet another XML cast issue (this is hopefully all of them 
now).
